METHOD OF OBTAINING SINTERED CERAMICS, CERAMIC, OBTAINED BY METHOD AND SPARK-PLUG, WHICH CONTAINS IT Russian patent published in 2013 - IPC C04B35/577 H01T13/38 

FIELD: chemistry.

SUBSTANCE: invention relates to field of semiconductor ceramic materials and can be used in production of spark-plugs. In accordance with claimed method, in liquid-containing reservoir mixed are from 50 to 75 wt % of compound, intended for formation of conducting phase and from 25 to 50 wt % of one or several materials, contributing to formation of isolating phases, consisting of silicon nitride and modified silicon oxynitride, resulting in ceramics sintering after thermal processing. SiC or MoSi₂ are preferably used as conducting phase. Mixture is crushed, dried and sieved, after which pressing of said mixture with further sintering is performed to obtain ceramics with from 0 to 30% porosity. Sintering is carried out under pressure equal at least 50 bars of gas which is not active with respect to mixture components.

EFFECT: obtaining ceramics with controlled microstructure, which makes it possible to increase product service term and reliability.
